FIELD OF THE INVENTION

The invention relates to medical equipment industry and, moreparticularly, to an angle rotation controlling device of a medicalsolution transfer system.

DESCRIPTION OF THE RELATED ART

Currently, most racks used for hanging the bottle of medical solutionare composed of a main pole and side brackets protruding from the mainpole. When patients need to be transferred, the transfer may not beeasily to carry out, because the rack is too big or too high. As aresult, the transfer time and efficiency may be affected, and the painof patients will be increased.

An object of the invention is to provide an angle rotation controllingdevice which is easily moved, rotatable, and height adjustable.

To solve the technical problem described above, the invention providesan angle rotation controlling device including a main pole. A left armand a right arm are assembled on the main pole, and both of the left armand the right arm can be rotated around the axis of the main pole. Twovertical rods are assembled at an end of left arm and right arm,respectively. A left arm tooth disc is assembled at a left arm's endwhich is coaxial with the main pole. The right arm tooth disc which ismatched with the left arm tooth disc is assembled at a right arm's endwhich is coaxial with the main pole. The left arm tooth disc and rightarm tooth disc are assembled on the main pole via a knob.

In order to fasten the main pole, the left arm and the right arm, a mainpole tooth disc is fixed at the bottom of the main pole to cooperatewith the left arm tooth disc.

In order to easily replace the main pole tooth disc, the left arm toothdisc and the right arm tooth disc when they have abrasion, the right armtooth disc is connected with the right arm via a fixing screw. The leftarm tooth disc is connected with the left arm via a positioning screwand protrusions at both sides. The main pole tooth disc is fastened tothe main pole via a pin.

In order to assure the height adjustability of the vertical rod, thevertical rod includes a fixing rod outside, and a telescopic rod inside.

In order to easily position the telescopic rod in the fixing rod, a pullbutton is disposed at the top of the telescopic rod, and an extraversivespring sheet(s) is(are) disposed at the body of the telescopic rod. Theextraversive part of the spring sheet(s) is(are) connected with the pullbutton, and the amount of the spring sheet(s) described above is atleast one.

In order to make the vertical rod stable in the vertical direction, theleft arm includes lower left arm(s) and upper left arm(s), and theamount of the upper left arm(s) is at least one. The right arm includeslower right arm(s) and upper right arm(s), and the amount of the upperright arm(s) is at least one.

The benefit of this invention lies in: by utilizing the structuredescribed above, the angle rotation controlling device can not only makethe left arm and the right arm rotate relatively, but also can make theleft arm and the right arm rotate around the main pole while the leftarm and the right arm are stationary relative to each other. The heightcan be adjusted at will, and the doctors and nurses can move thepatients easily.

DETAILED DESCRIPTION OF THE EMBODIMENTS

As shown in FIG. 1, FIG. 2 and FIG. 3, an angle rotation controllingdevice includes a main pole 3, and a left arm and a right arm areassembled on the main pole 3. Both of the left arm and the right arm arerotatable around the axis of the main pole 3. Two vertical rods 14 areassembled at an end of left arm and right arm, respectively. A left armtooth disc 9 is assembled at a left arm's end which is coaxial with themain pole 3, and a right arm tooth disc 8 which is matched with the leftarm tooth disc 9 is assembled at a right arm's end which is coaxial withthe main pole 3. The left arm tooth disc 9 and the right arm tooth disc8 are assembled on the main pole 3 via a knob 10. A main pole tooth disc5 is fixed at the bottom of the main pole 3 to cooperate with the leftarm tooth disc 9. The right arm tooth disc 8 is connected with the rightarm via a fixing screw 12. The left arm tooth disc 9 is connected withthe left arm via a positioning screw 11 and protrusions at both sides.The main pole tooth disc 5 is fixed to the main pole 3 via a pin 4. Thevertical rod 14 includes a fixing rod 14-2 outside, and a telescopic rod14-1 inside. The left arm includes lower left arm(s) 7 and upper leftarm(s) 1, and the amount of the upper left arm(s) 1 is at least one. Theright arm includes lower right arm(s) 6 and upper right arm(s) 2, andthe amount of the upper right arm(s) 2 is at least one.

When the knob 10 located at the bottom of the angle rotation controllingdevice is completely loosened, the upper left arm 1, the lower left arm7, the upper right arm 2 and the lower right arm 6 do not stay close tothe main pole 3. At that moment the teeth of the left arm tooth disc 9,the right arm tooth disc 8 and the main pole tooth disc 5 are completelyseparated, and the separate rotations of the upper left arm 1, the lowerleft arm 7, the upper right arm 2 and the lower right arm 6 around themain pole 3 are not affected. When the knob 10 is fastened, the left armtooth disc 9 and right arm tooth disc 8 stay close to each other, butthe main pole tooth disc 5 does not stay close to the left arm toothdisc 9 and right arm tooth disc 8. As a result, a fixed angle is formedbetween the upper left arm 1 and the lower left arm 7, and between theupper right arm 2 and the lower right arm 6, but the combination of theupper left arm 1 and the lower left arm 7 and the combination of theupper right arm 2 and the lower right arm 6 can still rotate around themain pole 3. When the knob 10 is further fastened, the main pole toothdisc 5 and the left arm tooth disc 9 stay close to each other, so as tomake all the upper left arm 1, the lower left arm 7, the upper right arm2 and the lower right arm 6 fastened tightly to the main pole 3. Whenthere is a need to adjust the angle and the position, the user onlyneeds to loosen the knob 10, rotate the upper left arm 1, the lower leftarm 7, the upper right arm 2 and the lower right arm 6 to a fixedposition, and then fasten the knob 10 to achieve the desired results. Abottle hook 15 is disposed at the top of the vertical rod 14 for hangingthe bottle of medical solution conveniently.

As shown in FIG. 4, a pull button 18 is disposed at the top of thetelescopic rod 14-1, and extraversive spring sheet(s) 17 is(are)disposed on the body of the telescopic rod 14-1. The extraversive partof the spring sheet(s) 17 is(are) connected with the pull button 18. Inthe invention, the amount of the spring sheet(s) 17 described above isat least one.

When the vertical rod 14 is operated, the user only needs to lift thepull button 18, and the pull button 18 drives the spring sheet 17 toshrink inwardly, so the telescopic rod 14-1 can be moved upwardly ordownwardly. When the needed position is arrived, the user only needs torelease the pull button 18, the spring sheet 17 recovers to the originalshape, and is clipped to the fixing rod 14-2, so that the heightadjustment is finished.
